Working from our base in Delhi(India), our company is a well-established provider in the industry. With the assistance of our reliable transportation facilities, we have become capable of delivering the orders on time. A Why Earth Resistance should be low? No electrical circuit either single phase or three phase is complete without proper earthing. The name Earthing is associated with . Earth strips, Earth plate. Earth electrodes . Proper fasterning or welding . Earth resistance . Soil resistivity Unless all these are Stable and Healthy the word good earthing wil have no meaning or value. To appreciate why earth resistance must be low, you need only use Ohms Law : E =Ftxl, where E is volts, R the resistance in ohms and I the current in amperes. Example : A 10 HP Motor is connected to a 3-phase 440 V (phase to phase 440V, phase to neutral 230V) supply with a fuse of 30 Amps. Now assume that an exposed wire touches the frame of the motor that is connected to a grounding system, which has 20 ohm resistance to earth. By Ohms Law the fault current developed would be BOY (phase to neutral)/ 20 Ohms= 11.5 Amps, and this fault current flows from the motor conductor to the earth. Since the fault current is 11.5 Amps against the fuse provided of 30 Amps, the fuse would not blow. If a person happens to touch the motor frame, he could be subjected to heavy electric shock of 230Volts to ground. as the fault current takes the path of least resistance, viz. through the person In this case, causing shock, bum Injuries and finally death due to cardiac arrest. If however, the earth resistance is kept less than I Ohm, the fuse would blow for the fault current of 230W I Ohm = 230 Amps. By keeping the earth resistance value close to 1.0 Ohm, the entire electric system would be healthy. In a 230 V system 30 mA current Is sufficient to cause instantaneous death. Benefits of Earthing with our Electrodes . Low impedance earthing . Ensures safety of life and property from
